Success Report on Innovative Conductive Binder
consisting of ideal conductive network on electrodesII
Material development in adding a conductivity by modified PVdF binder are popular in LIB application, but nobody
could discover a strong enough and elastic conductive binder upon enhancing a dispersibility of conductive agent.
Nowaday, we could achieve this innovative conductive binder having an adhesion part with pedestal form between
active materials. Besides, this adhesion part is of elastic bonding property and also make many spaces surrounding
active material particles to be fulfilled with small or fine active material particles, so called, a close-packed structure
of electrodes. In addition, this mechanism leads out reducing remarkably a volume of binder in use by 40 to 60 wt.% in
comparison with as 100 wt.% of conventional PVdF binder. The performance of each electrodes are almost same initial
chemical electrical properties as that of conventional PVdF in use. But IR drop and higher rating properties are superior
with CBC binder one to conventional binder one.

CB binder assist forming uniform and close-packed filling structure of electrodes to result in reducing the total
volume of binder in each formulation of each active material by means of measuring the proper absorption volume
of NMP solvent toward a conductive agent. This right volume predetermined should be minimum requiring volume
of CB binder to obtain optimum rheology of the coating solution of electrodes. It is the most critical notice in replacing
from conventional PVdF binder to CB binder in each application.

@@@@ conference center from June 18-22, 2018,
| We are promoting to sell various kinds of Battery Materials such
as Ionic Liquid(IL), zero solvent IL recipe electrolyte, imide salt as
Li-TFSI and Li-FSI,@various Cathode and Anode electrode using
conductive binder, Ion Conducive Polymer matrix -solid state
electrolyte hybrid membrane sheet and its system technology
under our position of "All-round player for LIB".
Whenever you are interested in any consultation in the field of
materials and technology in LIB application, we welcome your
contact to cope with your requirements.
This is the contact details.
We have this time joined Batteries 2017 exhibition held
in Nice, France during 4th and 6th October, 2017.
| It was mainly introduced Ion Conductive Polymer(so called ICP) and its derivatives for use in LIB applications.
This multi-Function Ion Conductive Polymer is of compositing basically by synthesizing PolyVinylidene DiFluoride
(so called PVdF) with Ionic Liquid to enhance ion conductivity property on resin polymer under nonconductive
proper The product structure of TREKION CP series is consisted of two backbones in molecule range of resin
polymer like PVdF as a main polymer and in molecule rate of synthesizing Ionic Liquid (so called I L) as the term
of Ion Conductive Rate ( ICR ) in the range of low to high molecule %with three standard grades. Nowadays, it is
available to supply solvent solution grade by dissolving TREKION ICP into N?Methyl-2-pyrolidone (so called NMP),
Dimethyl sulfoxide (so called DMSO), Acetonitrile, etc.
In the Exhibition Booth No. 647, we introduced the six fields in the LIB business range.@@
